The impact of climate change for the short, mid and long term horizons is investigated for an area along the Scheldt river, at the confluence with the Dender river. The downstream coastal boundary comprises of the sea level rise and storm surges from the North Sea while the upstream inland boundary comprises of rainfall and related runoff discharges. The third surface boundary comprises of wind
speed and direction along the Scheldt. The climate change scenarios are based on statistical analysis of an ensemble of (at least 20) simulation results with Regional Climate Models (RCMs). The RCM results are provided by the CERA database, the EU-FP5 PRUDENCE and the EU-FP6 ENSEMBLES database. Outputs of precipitation, temperature, potential evapotranspiration, wind speed, wind direction and Sea
Level Pressure (SLP) have been validated for historical periods and correlations are accounted for when quantifying future changes till 2100.
